TROLLEY-HANGER.

To all whom it? may coma-n.-

Be it known that I, RoYDEN O. CoUCi-I, a citizen of the United, States,residing at Charleston, in the county of Kanawha and State'of VestVirginia, have invented certain new and useful Improvements in TrolIcy-Hangers, of which the following is a specification.

My invention consists of means whereby the wire engaging members of thehanger are secured to the wire through means which may simultaneouslyeffect the securing of the wire engaging members to their own supportingmeans, the arrangement of these parts being such that they may be easilyseparated for the removal and insertion of the wire; and my inventionfurther consists of the parts and combination of parts as will .behereinafter more definitely set forth. I

A further object of my invention is to provide hangers with meansadapting them to fit onany standard hanging element.

In the drawing, Figure 1 is an end elevation of a trolley hangerembodying my invention; Fig.2 is a top plan view of the same partly insection; Fig. 3 is a view illustratingthe employment of the hanger tocatenary work; Fig. 4 is a transverse sect-ional view of Fig. 3, on theline 3-'3; Fig.

, 5' is a detail view, parts being broken away,

of the lug on one of the hangers; and Fig. 6 1s a detail view, partsbeing broken away,

of the lug on the other se tion of the hanger.

The trolley wire clamps a and 6 are illus trated as being constructed atthe lower ends to clamp a coming-tinwire 7 having the cross section of afigure 8. These clamps have a swell Salient midway their length, onwhich are formed seats 9 adapted to receive respectively. the head 10 ofthe bolt and the nut '11 of the -bolt, said bolt being designatedby thenumeral 12.

In the embodiment shown in Figs. 1 and 2, the-jaws 5 and 6 are providedwith neck portions 13- and 14, on the interior of each -of which arealining thread sections 15,

which thread sections are held in their alined relation through themedium of engaging lugs 16. These lugs are formed integrally with, andin pairs on the neck portions, and in their locking relation, embracethe neck portions of their respective opposed sections. The lockingeffect of the lug 16 is such that the jaws 5 and 6 will be held in theirproper relation and yet have sufficient Patent-ed Nov. 26, 1912.

1911. Serial No. 629,174.

Figs. 3 and 4 show an embodiment of my inve..tion particularly adaptedfor catenary work, in which embodiment, the lugs corresponding to thelugs 16 shown in Figs. 1=

and 2 are arranged upon the inner meeting edges of the clamping membersinstead of upon the outer edges, as illustrated in the other figures. Inthese figures, namely, Figs. 3 and 4. the clamping members 17 and 18 andthe clamping bolt 12 are of the same construction as illustrated anddescribed in connection with Figs. 1 and 2, and therefore need nofurther detail' description. The necks 1S) and. 20 of the sections 17and 18 are each provided with an annular groove 21 in which is fitted asplit ring 22. The abutting edge of the neck portion 20 is provided witha conical lug or projection 23, while' the neck portion 19 is providedwith a lug or projection 24 having a counter-sink 25 of a shape adaptedto receive and have a snug fit with the conical lug 23 on the oppositeneck member. The lug 24 is circular.

For supporting the trolley holding jaws from the messenger engagingmembers, the supporting strap .26 is provided near its lower end with anaperture through which the lug 24 is adapted to project when the strapis fitted to the hanger sectionand is clamped on the lug 24 by means ofthe neck portion 20, with its conical lug 23 entering the recess in thelug 24: as clearly illustrated in the sectional view, Fig. 4. Theseveral embodiments shown in the drawings are I e adapted for use. 1nany standard hanger.

The absence of the usual intricate joints on suchstruct-ures, which aresubject to rust or corrosion, adapt these constructions particularly foruse in mines.

From the above, it will be seen that a hanger constructed according tomyinvention is simple, cheap to manufacture and possesses maximumstrength.

1. A trolley hanger comprisinga pair of wire engaging members havingeach a threaded neck portion, a bolt uniting said members, and a pair oflugs on the rack portion of each of said men'ibers adapted to embracerespectively the neck portions of the adjacent members and hold thethreaded i sections thereof in position to receive a supporting bolt.

' 2. A trolley hanger comprising a pair of Wire engaging members havingeach a neck portion, a bolt unltmg the members, said neck portionshaving inter-engaging eleon said neck portions having inter-engage-Copies of this patent may be obtained for mentand providing a lock forthe vvire en-. gaging members, and a support engaged by saidinterlocking members and providin a support for the hanger, and a boltunitmg.
